发展杨树生产对沅江市血吸虫病抑制和环境影响的初探

Impacts of Poplar Plantings on Schistosomiasis and Environment in Yuanjiang

通过对沅江市杨树生产的初步研究,着重讨论了杨树生产对沅江市区域经济和生态环境的影响。通过研究发现:大面积种植杨树能有效抑制钉螺的生长和繁殖,在一定程度上控制血吸虫病蔓延;带动当地家具业等相关产业的发展,提高了当地居民的收入;对当地居住环境的改善,防洪治水有着积极的意义。同时,大面积种植单一树种,也对湖区的湿地环境产生了一系列的不良影响。

An analysis was conducted on Poplar plantings to study the impacts on regional economy and environment. It was found that large areas of Poplar plantings suppressed the growth and reproduction of snails, therefore reducing the spread of Schistosomiasis to a certain degree, meanwhile promoted the development of local furniture industry, improving the income of local residents. Poplar plantings have significant implications to improving the living conditions of local people and preventing floods. However, large areas of monoculture Poplar plantings also impose negative environmental impacts on the wetland.
